According to a poll done in 2010, 58% of adults aged 25-29 had only a cell phone (no landline). Assume that two randomly selected adults (aged 25-29) are asked whether they have only a cell phone. Complete parts a through e below. a. If a person has only a cell phone, we will record Y (for Yes). If not, we will record N. List all possible sequences of Y and N for this experiment. O A. YY, YN, NN O B. YY, YN, NY, NN O C. Y, N, YY, YN, NY, NN O D. YY, YY, YN, NY, NN, NN b. For each sequence, find by hand the probability that it will occur, assuming each outcome is independent. Select the correct choice below and fill in the answer boxes to complete your choice. (Type integers or decimals. Do not round.) O A. P(YY) = , P(YN) = , P(NY) , P(NN) = O B. P(YY) = , P(YY) = , P(YN) = . P(NY)= . P(NN)= , P(NN) = O C. PM) = , P(N) = , P(YY)= , P(YN) = , P(NY) = , P(NN) = O D. P(YY) = , P(YN) = , P(NN) = c. What is the probability that neither of the two randomly selected adults has only a cell phone? The probability that neither of the adults have only a cell phone is]. (Type an integer or decimal rounded to four decimal places as needed.) d. What is the probability that exactly one person out of two have only a cell phone? The probability that one of the adults has only a cell phone is
